Fig. 1 Sectional view of the weapon
Both the barrel and slide are engaged by rollers and locked together as an assembly.
Recoil move the slide assembly to the rear, compressing the recoil spring. The roller cam,
which retains the rollers in locked position, rests against a similarly configured frame lug.
After overcomming short recoil (6 mm), the rollers are disengaged and the barrel lug abuts
the frame as the slide continues reawards. The case is extracted and is ejected through the
port by the frame mounted ejector.
Trigger mechanism is of the single-action type. The firing pin is equipped with an
automatic safety catch preventing firing until the trigger has been pulled. This prevents an
accidental discharge of the weapon, even with an unintentional impact onto the hammer.
The frame-mounted safety has three positions. The lower is the "fire" mode and exposes
a red detent. In the middle position, the safety engages both, the trigger bar and the rebound
notch of the hammer. This allows the weapon to be "cocked and locked" or safety unloaded.
The upper position, provides a decocking function that causes the hammer to fall as the
safety rotates into the rebound notch of the hammer.
Pistol stripping and assembling is very simple, cleaning and maintenance require only
minimum time and work.
The pistol has been completely overhauled. After simple barrel exchange is given the
possibility to fire the weapon in corresponding calibre.
STRIPPING & ASSEMBLING
The weapon can be stripped down into folowing assemblies, Fig. 2:
2. Barrel with return spring
Fig. 2 The weapon stripped
1 . Remove the magazine by pressing the magazine catch. Retract the slide, checking the
chambre to insure that the pistol is unloaded. Allow the slide to return to battery and elevate
the safety to its uppermost position causing the hammer to fall against the hammer block.
2. Pull down the serrated tabs of the takedown latch located on both sides of the frame in
front of the trigger guard, Fig. 3a. This releases the slide assembly to move 6 mm forward
and lift straight up off the frame.
3. Invert the slide assembly and insert a magazine bottom plate extension in the slot in the
roller cam, Fig. 3b. Retain the slide with one hand while moving the roller cam forward to
disengage the rollers from the slide recesses. With the bottom plate extension canted
slightly to the rear, tilt the breech of the barrel assembly out about 1 0° and withdraw it to the
rear. Take recoil spring off the barrel.
Fig. 3 Stripping
1. Place the recoil spring on the barrel assembly than place the front end of the recoil
spring in the muzzle of the slide. Insert a magazine bottom plate extension in the slot in the
roller cam to move the muzzle of the barrel forward through the front of the slide. Lower the
breech of the barrel assembly into the slide allowig it to retract into position.
2. Place the slide assembly on the frame in the 6 mm forward position, aligning the lugs
and assembly slots. Apply downward pressure and move the slide to the rear until the
takedown latch snaps into place to engage and retain the slide.
3. Install the magazine to complete reassembly.
